Power of music in Unity
Objective: Add background music to frame the game mood
Sound is a powerful sense, second only to sight, and every game uses a sound tract to set the mood of the game. The combination of melody, harmony, rythym and orchestrations sets the mood for your game. In this case, fast driving techno rhythm sets the tension as the as the enemies appear. Create an empty 3D game object named Audio_Manager, and a second empty 3D object named Background as a child of the Audio_Manager. Audio in Unity requires an Audio Source component, so add an audio source to the Background within the Audio_Manager. Check both play on awake and loop so that it starts as the game begins and continues throughout the game.
Assign the music_background from GameDevHQ FileBase to the AudioClip for the Audio Source component.
Put on your headset and press play.
